“…Depression was evaluated using a self-reported Brief Job Stress Questionnaire (BJSQ) published in a research report on stress in the workplace and its impact on workers’ health [ 5 ]. The BJSQ was developed in Japan with the support of the Japanese Ministry of Labour and has been widely used in Japan to evaluate work-related stressful situations in various clinical and occupational settings [ 6 , 7 , 8 , 9 , 10 ]. In the BJSQ, six items, such as “I feel sad,” are used to measure workers’ depression.…”

The aim of this study was to investigate associations of workplace bullying and harassment with headache, stiffness of the neck or shoulders, lumbago, and pain of two or more joints. The subjects in this cross-sectional study were recruited from workers (n = 1,913) at 35 healthcare or welfare facilities in Japan. Because of non-participation or missing data, the number of subjects included in the analysis varied (response rate ≥ 77.1%). Workplace bullying and harassment were assessed using the Negative Acts Questionnaire. Depression was assessed using the Brief Job Stress Questionnaire. The frequency of pain experienced by workers in the previous month was evaluated using a four-point scale. Many of the associations of person-related bullying, work-related bullying, and sexual harassment with headache, stiffness of the neck or shoulders, lumbago, and pain of two or more joints were positive and significant (p < 0.05). Even after adjustment for depression, some of the associations remained significant (p < 0.05). For example, changes in the prevalence ratio for headache associated with a 1-point increase in the work-related bullying score were 1.05 (95% confidence interval (CI) 1.01 to 1.09) in men and 1.03 (95% CI 1.01 to 1.05) in women after adjustment for age, marital status, employment status, work shift, and depression.

“…The responses to these items were scored on a 4-point Likert-type scale (1 = agree; 2 = somewhat agree; 3 = somewhat disagree; and 4 = disagree). To evaluate social support from supervisors and co-workers, the reversed total score was calculated for each of the three questions with higher scores denoting higher social support (Otsuka et al 2009;Saijo et al 2013). Cronbach's alpha coefficients for the BSJQ subscalesjob demand, job control, and social support from supervisors, from co-workers, and from family/friends, were 0.81, 0.74, 0.95, 0.86, and 0.86, respectively.…”

Shortage of healthcare workers is a global problem. It is important to clarify factors, including job stress, that influence workplace resignation and factors that cause burnout among rural physicians. The study was designed as a cross-sectional questionnaire survey. We sent questionnaires to town or village hospitals and clinics (n = 1,898) in Hokkaido, Tohoku, Shikoku, and Kyushu and Okinawa. The number of participants was 509. Of these 7.7% were female and 21.6% were< 50 years. Internal or general medicine physicians were asked about personal and job factors, job stress based on the demand-control-support model, intention to resign from current position, and burnout evaluated using the Maslach Burnout Inventory-General Survey. Overall, 10.4% of the participants intended to resign, and 21.8% was defined as burnout positive. In the multivariate logistic regression analysis, dissatisfaction with income (OR, 3.63; 95% CI, 1.63-8.10), having one's hometown in another town or village in the same prefecture (OR, 3.53; 95% CI, 1.18-10.62) were significantly related to intention to resign, while high job control (OR, 0.72; 95% CI, 0.58-0.88) had a significantly protective effect. In the multivariate analysis, high job demand (OR, 1.48; 95% CI, 1.28-1.72) was significantly related to burnout, and high job control (OR, 0.66; 95% CI, 0.55-0.78) and high support from co-workers (OR 0.88, 95% CI, 0.78-1.00) had a significantly protective effect. Improving job stress factors, especially job control, and taking into consideration physicians' hometown and income may be important factors to prevent resignation from a current position and burnout among Japanese rural physicians.

“…A number of studies have related these data to job performance, job satisfaction, presenteeism, and depressive status (Kawada and Otsuka 2011;Inoue et al 2016;Saijo et al 2016Saijo et al , 2017Sugawara et al 2017;Oh et al 2017), but most of them were done by use of subjective outcome variables resulting from a questionnaire method. In this sense, there are few reports using objective outcomes (Collins et al 2005;Otsuka et al 2009;Maeda et al 2015). QT intervals, as well as heart rate variability (HRV) and heart rate, have been considered as an objective marker of the development of ventricular arrhythmia or of the susceptibility to sudden death (El-Sherif and Turitto 2003;Jouven et al 2005), because QT intervals represent the duration between ventricular depolarization and subsequent repolarization (Yun et al 2015) while the corrected QT interval (Bazett 1920), by comparison with QT index (Rautaharju et al 2009), tends to depend on heart rate .…”

“…Regular exercise was defined as at least one 30-min session at least once per week. Sleep duration (min) was computed as the difference between bedtime and wake time on workdays.Job stress and home stress: The BJSQ was employed to evaluate job demand, job control, and social supports (i.e., supervisor and coworker supports), and has been widely used in Japan for practical occupational health evaluation and occupational health research (Fukuoka et al 2005;Harada et al 2005;Otsuka et al 2009). Each dimension comprised three questions with responses being scored on a 4-point Likert scale (1 ="agree"; 2 ="somewhat agree"; 3 ="somewhat disagree"; and 4 ="disagree") (Saijo et al 2016): Concerning job demand, i) you have to do an enormous amount of work, ii) you cannot complete all your work in the allotted time, and iii) you have to work very hard.…”

There is little epidemiological evidence linking subjective stress to objective etiologic indicators. To clarify an association between work-related stress and autonomic nervous function, we examined call center employees (167 males and 371 females) undergoing electrocardiography (ECG) at the time of annual health checkups. The questionnaire was composed of the Brief Job Stress Questionnaire based on the demand-control-support model and the Social Readjustment Rating Scale including detailed contents of home stress. The Bazett's corrected QT (QTc) interval, QT index, and heart rate were obtained from the ECG data. The male employees showed significantly higher scores of job demand, job control, and supervisor support than the female ones. In the male employees, QT index indicating the extent of autonomic imbalance and heart rate were associated with high score of supervisor support and low score of coworker support (P < 0.05), but no significant relationships were seen between QTc interval and either job strain (i.e., job demand and job control) or home stress. By contrast, the female employees showed no significant links between any autonomic indicators and either work-related stress or home stress. These data suggest that work-related stress affected QT index in male employees suffering specific occupational stressors such as emotional abuse from unsatisfied customers. Specifically, supports from supervisors and coworkers were paradoxically associated with QT index, implying that supervisors may have failed to effectively support such male employees. Also, autonomic nervous function in male employees appears to be more vulnerable to work-related stress than that in female ones.Keywords: autonomic nervous function; call center employees; demand-control-support model; electrocardiography; subjective job stress Tohoku J. Exp. Med., 2017 December, 243 (4), 321-328. © 2017 Tohoku University Medical Press IntroductionWith regard to the epidemiological evidence linking work-related stress to cardiovascular disease, the stress and cardiovascular disease are not directly tied but mediated by a certain etiologic mechanism. However, there is less research on the etiological pathways of the disease causation (Schnall et al. 1994). Collins et al. (2005) examined electrocardiographic QT intervals for 36 healthy men wearing 48-h Holter-monitor, and one mechanism suggested by them was the disturbed cardiovascular regulatory pattern associated with job strain in a pathogenic manner. In this case, it may not be easy to examine a large number of workers with 48-h monitor. Another mechanism was concerning autonomic imbalance induced by home stress (Maeda et al. 2015), but not work-related stress. For the earlier prevention of work-related cardiovascular events and a better understanding of the pathophysiology, it is important to investigate the association between workrelated stress and autonomic outcomes by using simpler tools.As a measure of work-related stress, the job demandcontrol-support (DCS) model with three dimensions (i...
